ABSTRACT:
A numerical control device used in conjunction with a machine tool including a spindle head having a plurality of tapping tools is provided with a tapping pitch data group memory which stores the tapping pitch of each tool. Upon selection of a tool according to a machining program, a corresponding data group is retrieved from memory and from this data group an average tapping pitch is obtained. According to the average value thus obtained, a suitable feed rate is selected.
